If a nuclear emergency occurs, sharing information with neighbouring countries is crucial.
The communication procedures to be implemented in the event of a nuclear accident at Cattenom are the subject of a bilateral agreement between the Grand Duchy of Luxembourg and France.
In the event of an accident, the manager of the power station shall inform the Luxembourg authorities by means of the SELCA system, the System of exchange and liaison (Système d’échange et de liaison) between Cattenom and the authorities, a network of dedicated telephone lines. Rhineland-Palatinate and Saarland are also part of this system.
On a European level, the ECURIE alert system (European Community Urgent Radiological Information Exchange) enables Member States to exchange information in the event of a nuclear emergency.
This computer system, with a star-like configuration, enables a State to launch an alert if a nuclear accident that could have cross-border consequences occurs at one of its power plants.
